<p>很清晰，以本地启动的 nacos 为注册中心，服务名称为 memory-client。</p>
<p>启动项目后，看到这样的提示，那就说明已经该服务注册成功了：</p>

<p>其中，memory-core 作为 bubbo 服务提供者，其下三个 dubbo 服务也成功注册到 Nacos 注册中心：</p>

<p><strong>距离上次重构 Memory API 忆汇廊项目的代码有一个月了，补一下使用 Dubbo 实现远程服务调用的开发流程，以及注意事项。</strong></p>
<p>要保证接口开放平台的核心功能正常，最重要的当然是做到严格的权限校验和身份认证，避免出现恶意调取接口的情况。</p>
<p>我们选择把校验的代码逻辑，全部统一放到 Gateway 网关过滤器中完成，实现统一的请求过滤和身份认证。</p>
<p>在先前的网关实现中，我们已实现基于路由配置的请求转发到后端接口。</p>
<p>但随着新需求的发展，我们希望 memory-gateway 服务的代码量保持简洁。</p>
<p>为此，我们考虑将核心业务逻辑，如用户身份验证、接口存在性检查等，移至其他微服务中实现，而 memory-gateway 仅作为外部服务的调用者。</p>
<p>这涉及到分布式服务架构下的跨服务通信问题，关键在于如何在微服务间实现跨服务方法调用。</p>
<p>为满足这一需求，我们将引入 RPC 框架进行远程调用。</p>

<p>就这么简单的几行客户端代码，折腾了我好几天，总是报错还找不到解决方法。</p>
<p>首先，@RequestParam(value = “accessKey”)，这行代码必须加上。原因：</p>
<p><a target="_blank" rel="noopener" href="https://blog.csdn.net/he__xu/article/details/120892236">nested exception is java.lang.IllegalStateException: RequestParam.value() was empty on parameter 0-CSDN 博客</a></p>

<p>接下来就是 path = “/api/user/inner” 的配置了，这行代码要是不配置，直接找不到对应服务，报这个错：</p>
<p>feign.RetryableException: Connection refused: connect executing GET <a target="_blank" rel="noopener" href="http://memory-core/api/user/get/invoke?accessKey=memory">http://memory-core/api/user/get/invoke?accessKey=memory</a></p>
<p>看到这个恶心的错误没，没能在注册中心里找到对应服务。</p>
<p>为了解决这个问题，我还编写了 demo 测试代码，查看了下注册中心里到底有没有注册成功这个服务，都在上面 👆</p>
<p>最后是这个：</p>

<figure class="highlight java"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br><span class="line">16</span><br><span class="line">17</span><br><span class="line">18</span><br><span class="line">19</span><br><span class="line">20</span><br><span class="line">21</span><br><span class="line">22</span><br><span class="line">23</span><br><span class="line">24</span><br><span class="line">25</span><br><span class="line">26</span><br><span class="line">27</span><br><span class="line">28</span><br><span class="line">29</span><br><span class="line">30</span><br></pre></td><td class="code"><pre><code class="hljs java"><span class="hljs-keyword">package</span> com.memory.gateway.config;<br><br><span class="hljs-keyword">import</span> org.springframework.beans.factory.ObjectProvider;<br><span class="hljs-keyword">import</span> org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;<br><span class="hljs-keyword">import</span> org.springframework.boot.autoconfigure.http.HttpMessageConverters;<br><span class="hljs-keyword">import</span> org.springframework.context.annotation.Bean;<br><span class="hljs-keyword">import</span> org.springframework.context.annotation.Configuration;<br><span class="hljs-keyword">import</span> org.springframework.http.converter.HttpMessageConverter;<br><br><span class="hljs-keyword">import</span> java.util.stream.Collectors;<br><br><span class="hljs-comment">/**</span><br><span class="hljs-comment"> * ClassName: HttpMesConConfiguration</span><br><span class="hljs-comment"> * Package: com.memory.gateway.config</span><br><span class="hljs-comment"> * Description:</span><br><span class="hljs-comment"> *</span><br><span class="hljs-comment"> * <span class="hljs-doctag">@Author</span> Memory</span><br><span class="hljs-comment"> * <span class="hljs-doctag">@Create</span> 2024/6/14 22:35</span><br><span class="hljs-comment"> * <span class="hljs-doctag">@Version</span> 1.0</span><br><span class="hljs-comment"> */</span><br><br><span class="hljs-meta">@Configuration</span><br><span class="hljs-keyword">public</span> <span class="hljs-keyword">class</span> <span class="hljs-title class_">HttpMesConConfiguration</span> &#123;<br>    <span class="hljs-meta">@Bean</span><br>    <span class="hljs-meta">@ConditionalOnMissingBean</span><br>    <span class="hljs-keyword">public</span> HttpMessageConverters <span class="hljs-title function_">messageConverters</span><span class="hljs-params">(ObjectProvider&lt;HttpMessageConverter&lt;?&gt;&gt; converters)</span> &#123;<br>        <span class="hljs-keyword">return</span> <span class="hljs-keyword">new</span> <span class="hljs-title class_">HttpMessageConverters</span>(converters.orderedStream().collect(Collectors.toList()));<br>    &#125;<br>&#125;<br><br></code></pre></td></tr></table></figure>

<p>这个问题就完美解决了。</p>
<p>搞定了。</p>
<p>memory-backend-gateway 和 memory-backend-core-service 模块引入依赖：</p>
<figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><code class="hljs xml"><span class="hljs-tag">&lt;<span class="hljs-name">dependency</span>&gt;</span><br>     <span class="hljs-tag">&lt;<span class="hljs-name">groupId</span>&gt;</span>org.springframework.cloud<span class="hljs-tag">&lt;/<span class="hljs-name">groupId</span>&gt;</span><br>     <span class="hljs-tag">&lt;<span class="hljs-name">artifactId</span>&gt;</span>spring-cloud-starter-openfeign<span class="hljs-tag">&lt;/<span class="hljs-name">artifactId</span>&gt;</span><br> <span class="hljs-tag">&lt;/<span class="hljs-name">dependency</span>&gt;</span><br></code></pre></td></tr></table></figure>

<p>编写客户端，这边我新增了一个公共模块：memory-backend-server-client，客户端代码写这里了：</p>
<figure class="highlight java"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><code class="hljs java"><span class="hljs-comment">/**</span><br><span class="hljs-comment"> * 内部用户服务</span><br><span class="hljs-comment"> */</span><br><span class="hljs-meta">@FeignClient(name = &quot;memory-core&quot;, path = &quot;/api/user/inner&quot;)</span><br><span class="hljs-keyword">public</span> <span class="hljs-keyword">interface</span> <span class="hljs-title class_">UserFeignClient</span> &#123;<br><br>    <span class="hljs-comment">/**</span><br><span class="hljs-comment">     * 数据库中查是否已分配给用户秘钥（accessKey）</span><br><span class="hljs-comment">     *</span><br><span class="hljs-comment">     * <span class="hljs-doctag">@param</span> accessKey</span><br><span class="hljs-comment">     * <span class="hljs-doctag">@return</span></span><br><span class="hljs-comment">     */</span><br>    <span class="hljs-meta">@GetMapping(&quot;/get/invoke&quot;)</span><br>    User <span class="hljs-title function_">getInvokeUser</span><span class="hljs-params">(<span class="hljs-meta">@RequestParam(value = &quot;accessKey&quot;)</span> String accessKey)</span>;<br>&#125;<br></code></pre></td></tr></table></figure>

<p>memory-backend-gateway 启动类：</p>

<p>🥣 <a target="_blank" rel="noopener" href="https://doc.xiaominfo.com/docs/middleware-sources/spring-cloud-gateway/spring-gateway-introduction">Spring Cloud Gateway 网关聚合 | Knife4j (xiaominfo.com)</a></p>
<p>访问：<a target="_blank" rel="noopener" href="http://localhost:8090/api/doc.html#/home">localhost</a>，即可查看到聚合 API 文档，十分方便。</p>
<p>如果这里引用了 Gateway 请求过滤器，可能会有无权限访问的情况发生：</p>

<p>在权限校验中，选择直接放行聚合 API 文档访问：</p>
